DUPLICATE DATABASE USING RMAN





Duplicating a database using Recovery Manager  (RMAN)

NOTE: Here host name is same for both source & Target db's

 Following are the steps that we need to perform.

 Source Database :PRMY001

 Duplicate Database Name: DPRMY001

 --------------------------------------------------------------------------------------------------------------------------

 STEP 1: Create password for destination database.  In $ORACLE_HOME/dbs location like below.

 orapwd file=$ORACLE_HOME/dbs/orapwdprmy001 password=dprmy001 entries=3 force=y

 --------------------------------------------------------------------------------------------------------------------------

 STEP 2: Create necessary folders for destination duplicate database.

 [oracle@oradba dprmy001]$ ls    > List all files/Directories in  present DIR

 adump bdump cdump dpdump pfile scripts udump

 [oracle@oradba dprmy001]$ pwd  > Shows present working DIR


 /u01/app/oracle/admin/dprmy001

 --------------------------------------------------------------------------------------------------------------------------

 STEP 3: Create pfile for the destination database dprmy001. The below is an example for it. You can create it as per your location & requirements.

 *db_name=dprmy001
# note that the following two initialization parameters have equivalents
# on the DUPLICATE command itself
*DB_FILE_NAME_CONVERT=("/oradata/prmy001/","/oradata/dprmy001/")
*LOG_FILE_NAME_CONVERT=("/oradata/prmy001/","/oradata/dprmy001/")
*compatible='10.2.0.1.0'
*db_block_size=8192
*db_file_multiblock_read_count=16
*db_recovery_file_dest_size=2147483648
*job_queue_processes=10
*open_cursors=300
*pga_aggregate_target=94371840
*processes=150
*remote_login_passwordfile='EXCLUSIVE'

*sga_target=285212672

 --------------------------------------------------------------------------------------------------------------------------

 STEP 4: Create spfile from the pfile and open the destination database with nomount mode. Like below

 [oracle@oradba dbs]$ export ORACLE_SID=dprmy001

 [oracle@oradba dbs]$ sqlplus / as sysdba

 Connected to an idle instance.

 SQL> create spfile from pfile='/u01/app/oracle/product/10201/dbs/initdprmy001.ora';
File created.
SQL> exit
Disconnected

 NOTE: First Oracle search for the spfile in the default location, if the spfile is not available in that location, then oracle looks for the pfile.

[oracle@oradba dbs]$ sqlplus / as sysdba

SQL>

 --------------------------------------------------------------------------------------------------------------------------

 STEP 5: Check the source database – source database should be in open state if database is in archive

log mode.

 NOTE: If database is in noarchivelog mode it should be in MOUNT state.

 [oracle@oradba dprmy001]$ . oraenv

 ORACLE_SID = [dprmy001] ? prmy001

 [oracle@oradba dprmy001]$ sqlplus / as sysdba

------------------------------------ ----------- ------------------------------
spfile string /u01/app/oracle/product/10201/dbs/spfileprmy001.ora

 NOTE: Here database is in archivelog mode.

 -------------------------------------------------------------------------------------------------------------------

 STEP 6: Add necessary TNS Entries for the Destination database dprmy001 and check the status of
Listener,if the listener not started start the listener.

 STEP 7: Take the backup using RMAN for source database.

[oracle@oradba ~]$ rman target /

 STEP 7: Now connect to RMAN and issue the below script.

 [oracle@oradba ~]$ rman target /

 RMAN> connect auxiliary sys/dprmy001@dprmy001

 RMAN> run
{
allocate auxiliary channel c1 type disk;

ORA-39014: One or more workers have prematurely exited.ORA-00018: maximum number of sessions exceeded

ERROR: I was Performing a full database import and during the import I faced the below error. ORA-39014: One or more workers have prematurely exited. ORA-39029: worker 6 with process name "DW07" prematurely terminated ORA-31672: Worker process DW07 died unexpectedly. Job "SYSTEM"."SYS_IMPORT_FULL_04" stopped due to fatal error at 00:59:40 ORA-39014: One or more workers have prematurely exited. SOLUTION:  Run the import with fewer parallel processes, like PARALLEL=2 instead of 8. I was able to run the import successfully. NOTE 1: This errors occurs when there are less session allocation in the database. check the session,process parameters and increase them accordingly. To avoid such errors again. NOTE 2 : Note: Increasing processes parameter increases the amount of shared memory that needs to be reserved & the OS must be configured to support the larger amount of shared memory. So here we first need to increase the Memory & SG
